I've used it twice. The first time I couldn't load the route I wanted to ride because the Hammerhead dashboard was down, and you can't load routes directly. The second I got the route loaded, but the routing engine crash and the map screen spent the whole ride saying 'Waiting for instructions'. Despite setting of with 65% battery charge, the battery died after 75km. So far, I'm decidedly underwhelmed. It's got a very nice screen, but other than that - and in particular in terms of its functionality overall - it's still distinctly inferior to all its major competitors.
